Consolidation Actions Taken

1. ✅ Updated Task Backlog.md with new sections:

   • Section 8: Forecast & AR(1) Model
   • Section 9: Regime Clustering Enhancements
   • Section 10: Architecture & Code Quality

2. ✅ Updated Progress Summary:

   • Active Tasks: 25 → 61
   • Added consolidation notes
   • Updated last modified date

3. ✅ Added Consolidation Notices to audit documents:

   • State Management Audit ACM Main.md
   • Regime Audit.md
   • Forecast Audit.md
   • docs/Comprehensive Audit of acm main.md

4. ✅ Updated Supporting Documents:

   • Task Backlog.md - Added note about master document
   • docs/To Do.md - Marked as DEPRECATED

Benefits of Consolidation

1. Single Source of Truth: All tasks tracked in one master document
2. No Duplication: Eliminated redundant task tracking across multiple files
3. Clear Priorities: All tasks have assigned priorities (Critical → Low)
4. Traceability: Each task references its source audit document
5. Status Tracking: Clear status (Done/Pending/Planned/Deferred) for all tasks
6. Better Organization: Tasks grouped by functional area

---

Document Structure

The consolidated Task Backlog.md now contains:

1. Progress Summary - Overall metrics and recent completions
2. Sections 1-7 - Existing task categories (Analytics, Model Management, etc.)
3. Section 8 - NEW: Forecast & AR(1) Model (14 tasks)
4. Section 9 - NEW: Regime Clustering Enhancements (8 tasks)
5. Section 10 - NEW: Architecture & Code Quality (7 tasks)
6. Appendices - Train/Test terminology cleanup, performance analysis, etc.

---

Maintenance Guidelines

1. Single Update Point: Update only Task Backlog.md for task tracking
2. Audit Documents: Keep audit documents as historical reference, don't update
3. Completed Tasks: Move from Pending → Done with completion date
4. New Audits: Add new sections to Task Backlog.md following existing format
5. Regular Reviews: Update progress summary monthly

2025-11-14 Repository Delta Audit (SQL + Grafana)

This section records a light‑weight follow‑up audit after the first full consolidation, focusing on SQL integration outputs and Grafana dashboards.

A. SQL Outputs & Run Logging

• Status: SQL integration still ~89% complete, but core dual‑write path is functioning correctly for FD_FAN and GAS_TURBINE.
• Evidence: gas_turbine_test.log and fd_fan_coldstart.log show successful inserts into all key analytics tables:
  • ACM_HealthTimeline, ACM_RegimeTimeline, ACM_ContributionCurrent, ACM_ContributionTimeline, ACM_SensorHotspots, ACM_SensorHotspotTimeline, ACM_HealthZoneByPeriod, ACM_SensorAnomalyByPeriod, ACM_DefectSummary, ACM_DefectTimeline, ACM_SensorDefects, ACM_EpisodeMetrics, ACM_Episodes, etc.
• Run scoping: Many Grafana queries previously ignored RunID and mixed historical runs. Panels for health, contributions, defect timeline, drift and anomaly rates have now been updated to consistently scope to the latest RunID per EquipID where appropriate.

B. Grafana Dashboards & SQL Queries

• Created a new ACM Operator View dashboard (grafana_dashboards/acm_operator_dashboard.json) that reuses the same SQL tables but presents a simplified, run‑scoped story for operators.
• Tightened and documented queries in grafana_dashboards/docs/SQL_QUERIES_REFERENCE.md:
  • Clarified detector vs sensor semantics (DetectorType vs SensorName).
  • Added explicit RunID filters for “current/latest run” panels.
  • Pivoted ACM_HealthZoneByPeriod for stack‑bar views (GOOD/WATCH/ALERT per period).
  • Documented the Detector Explanations panel built from ACM_SensorDefects + ACM_DetectorMetadata.
• Added scripts/sql/56_create_detector_metadata.sql to define ACM_DetectorMetadata (per‑family explanations and operator hints).

C. Files Archived as Non‑Essential

The following files were moved to artifacts/archive/ as non‑essential runtime artefacts (logs/HTML exports). They can be deleted later without affecting code:

• Root logs / outputs:
  • batch_run_fd_fan.log, batch_run_gas_turbine.log
  • fd_fan_coldstart.log, gas_turbine_final_test.log, gas_turbine_test.log, pipeline_run.log
  • cond_pump_output.txt, test_output.txt
• HTML exports (redundant with markdown):
  • docs/SQL_INTEGRATION_PLAN.html
  • docs/SQL_MODE_STATUS.html
  • Task Backlog.html

These were left in place under artifacts/archive/ for traceability; the canonical sources are the corresponding .md documents and the SQL tables.

D. Open Follow‑ups (no new IDs added)

Rather than introducing new task IDs, the following should be tracked against existing sections in Task Backlog.md:

• Verify ACM_DriftEvents schema and populate it with rich drift event data (timestamps, values) so Grafana drift annotations become meaningful.
• Decide on a final visual for detector correlation (table with colored cells vs heatmap) and wire it to ACM_DetectorCorrelation.
• Consider adding per‑sensor anomaly‑rate aggregation if operators need a true “sensor × time” anomaly heatmap (new table derived from existing outputs).

No additional task IDs were added to the master backlog; these items can be recorded under the existing SQL/Visualization or Architecture sections as needed.
